  • How is crude pressed sunflower oil refined?
  • Crude pressed sunflower oil obtained from a local oil mill was refined using chemical method by degumming, neutralization, bleaching and dewaxing. The quality and composition of crude and refined oil were compared. The phosphorous content, FFA content, peroxide value and wax content decreased during the refining process.‌
  • Does degumming remove phosphorus and free fatty acids from sunflower oil?
  • Abstract Currently, two major methods of oil refining are widely used: chemical and physical refining. This study compared the effects of these processes, including degumming, bleaching, neutralization, and deodorization, on the removal of phosphorus, free fatty acids, and the loss of tocopherols in sunflower oil.‌
  • What is the difference between physical and chemical refining of sunflower oil?
  • Tocopherol loss during physical refining was higher by 10% than in chemical refining due to the high temperatures used during the deodorization process, which removes free fatty acids in sunflower oil. In chemical refining process, sunflower oil retained more tocopherols compared to the physical refining method.‌
  • Can sunflower oil be refined?
  • An experimental oil refining unit has been developed and tested for refining of sunflower oil. Crude pressed sunflower oil obtained from a local oil mill was refined using chemical method by degumming, neutralization, bleaching and dewaxing. The quality and composition of crude and refined oil were compared.‌
  • Does sunflower oil retain more tocopherols in chemical refining process?
  • In chemical refining process, sunflower oil retained more tocopherols compared to the physical refining method. However chemical refining is considered less efficient due to saponification of neutral oil. 1. Introduction Vegetable oils are obtained through two primary methods: pressing and extraction.‌
  • How is crude sunflower oil degummed?
  • For the physical refining process, crude sunflower oil was degummed using the TOP degumming method. In this process, the oil was treated with 0.3% w/w phosphoric acid (75% w/w), and the H3PO4 was neutralized with 0.15% w/w sodium hydroxide (40% w/w).
